Another plant that was brought (from Japan) for the same reason is kudzu. It is everywhere in Georgia, North and South Carolina, and is a huge problem. There is a lot of work being done to find or create good uses of this plant, which actually looks quite pretty until you realize it's smothering other kinds of growth. Nancy told me of a friend of hers who is using it very creatively.
Of course there is the Spanish moss, which is neither Spanish nor is it moss. But it's fascinating. (That's R&C on the left).
Remember in the Part II when I mentioned DC and his brother reverting back to their childhood personas when they are together? Check this out.
